Question 01

Discussion : We can see that, in this transformation function, pixels with intensity values between 50 and 150, are increased but other intensities are not changed. We can see this result in the above-transformed image. The intensities of gray pixels of the original image are increased so that we can see a clear white region on her face. But dark and white pixels are not changed.

Question 02

Discussion : In this transformation, we can see that a wide range of dark pixels are mapped into a narrow range of dark pixels and a narrow range of white pixels are mapped into a wide range of white pixels. Therefore, we can see that the details of white matter are more highlighted compared to gray matter. We can extract more information about white matters.
